Self- governing control is a defining characteristic of autonomous computing machinery. Autonomy implies some degree of independence, and when a system's ability to achieve its mission is independent of how it is initialized, the system is self-stabilizing. Application of self-stabilization to system and network components is motivated by core concerns of fault-tolerance in distributed systems. Self-stabilization is a solution to problems of transient memory faults and systems with dynamic reconfigurations. Research in self-stabilization explores many of the classic themes of distributed computing (distributed graph algorithms, mutual exclusion, distributed agreement). Recent papers combine self-stabilization with traditional forms of fault-tolerance, consider methodological issues for the design of self-stabilizing systems, investigate randomized techniques, and apply stabilization to new networking models. The workshop brings together concerns from theory and practice of self-stabilization.

This book aims at being a comprehensive and pedagogical introduction to the concept of self-stabilization, introduced by Edsger Wybe Dijkstra in 1973. Self-stabilization characterizes the ability of a distributed algorithm to converge within finite time to a configuration from which its behavior is correct (i.e., satisfies a given specification), regardless the arbitrary initial configuration of the system. This arbitrary initial configuration may be the result of the occurrence of a finite number of transient faults. Hence, self-stabilization is actually considered as a versatile non-masking fault tolerance approach, since it recovers from the effect of any finite number of such faults in a unified manner. Another major interest of such an automatic recovery method comes from the difficulty of resetting malfunctioning devices in a large-scale (and so, geographically spread) distributed system (the Internet, Pair-to-Pair networks, and Delay Tolerant Networks are examples of such distributed systems). Furthermore, self-stabilization is usually recognized as a lightweight property to achieve fault tolerance as compared to other classical fault tolerance approaches. Indeed, the overhead, both in terms of time and space, of state-of-the-art self-stabilizing algorithms is commonly small. This makes self-stabilization very attractive for distributed systems equipped of processes with low computational and memory capabilities, such as wireless sensor networks. After more than 40 years of existence, self-stabilization is now sufficiently established as an important field of research in theoretical distributed computing to justify its teaching in advanced research-oriented graduate courses. This book is an initiation course, which consists of the formal definition of self-stabilization and its related concepts, followed by a deep review and study of classical (simple) algorithms, commonly used proof schemes and design patterns, as well as premium results issued from the self-stabilizing community. As often happens in the self-stabilizing area, in this book we focus on the proof of correctness and the analytical complexity of the studied distributed self-stabilizing algorithms. Finally, we underline that most of the algorithms studied in this book are actually dedicated to the high-level atomic-state model, which is the most commonly used computational model in the self-stabilizing area. However, in the last chapter, we present general techniques to achieve self-stabilization in the low-level message passing model, as well as example algorithms.

Abstract: "A self-stabilizing system is a network of machines, which starts from an arbitrary initial state and always converges to a legitimate configuration in a finite number of steps. Dijkstra, in his 1974 CACM paper, first demonstrated the feasibility of designing self-stabilizing systems. This report analyzes two of his three protocols, and evolves a methodology for designing non-trivial self-stabilizing systems. To demonstrate the feasibility of this methodology, Dijkstra's solutions have been extended to graph topologies. Finally, the importance of self-stabilizing systems have been highlighted with possible potential applications in different areas."

The papers in this volume were presented at the 11th International Sym- sium on Stabilization, Safety, and Security of Distributed Systems (SSS), held November 3–6, 2009 in Lyon, France. SSS is an international forum for researchers and practitioners in the design anddevelopmentoffault-tolerantdistributedsystemswithself-*attributes,such as self-stabilization, self-con?guration, self-organization, self-management, se- healing, self-optimization, self-adaptiveness, self-protection, etc. SSS started as theWorkshoponSelf-StabilizingSystems(WSS),the?rsttwoofwhichwereheld inAustinin1989andinLasVegasin1995.Startingin1995,theworkshopbegan to be held biennially; it was held in Santa Barbara (1997), Austin (1999), and Lisbon (2001). As interest grew and the community expanded, in 2003, the title of the forum was changed to the Symposium on Self-Stabilizing Systems (SSS). SSS was organized in San Francisco in 2003 and in Barcelona in 2005. As SSS broadened its scope and attracted researchers from other communities, a couple of changes were made in 2006. It became an annual event, and the name of the conferencewaschangedto the InternationalSymposiumonStabilization,Safety, and Security of Distributed Systems (SSS). The last three SSS conferences were held in Dallas (2006), Paris (2007), and Detroit (2008).

This volume contains the proceedings of the 10th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS), held November 21–23, 2008 in Detroit, Michigan USA. SSS started as the Workshop on Self-Stabilizing Systems (WSS), which was ?rst held at Austin in 1989. From the second WSS in Las Vegas in 1995, the - rum was held biennially, at Santa Barbara(1997),Austin (1999), Lisbon (2001), San Francisco (2003) and Barcelona (2005). The title of the forum changed to the Symposium on Self-Stabilizing Systems (SSS) in 2003. Since 2005, SSS was run annually, and in 2006 (Dallas) the scope of the conference was extended to cover all safety and security-related aspects of self-* systems. This extension followed the demand for self-stabilization in various areas of distributed c- puting including peer-to-peer networks, wireless sensor networks, mobile ad-hoc networks, robotic networks. To re?ect this change, the name of the symposium changed to the International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS). This year we received 43 submissions from 13 countries. Most submissions were from the USA and France. Each submission was carefully reviewed by three to six Program Committee members with the help of external reviewers.

Self-stabilization [2] is a versatile technique for recovery from erroneous behavior due to transient faults or wrong initialization. A system is self-stabilizing if (1) starting from an arbitrary initial state it can automatically reach a set of legitimate states in a finite number of steps and (2) it remains in legitimate states in the absence of faults. Weak-stabilization [3] and probabilistic-stabilization [4] were later introduced in the literature to deal with resource consumption of self-stabilizing algorithms and impossibility results. Since the system perturbed by fault may deviate from correct behavior for a finite amount of time, it is paramount to minimize this time as much as possible, especially in the domain of robotics and networking. This type of fault tolerance is called non-masking because the faulty behavior is not completely masked from the user [1]. Designing correct stabilizing algorithms can be tedious. Designing such algorithms that satisfy certain average recovery time constraints (e.g., for performance guarantees) adds further complications to this process. Therefore, developing an automatic technique that takes as input the specification of the desired system, and synthesizes as output a stabilizing algorithm with minimum (or other upper bound) average recovery time is useful and challenging. In this thesis, our main focus is on designing automated techniques to optimize the average recovery time of stabilizing systems using model checking and synthesis techniques. First, we prove that synthesizing weak-stabilizing distributed programs from scratch and repairing stabilizing algorithms with average recovery time constraints are NP-complete in the state-space of the program. To cope with this complexity, we propose a polynomial-time heuristic that compared to existing stabilizing algorithms, provides lower average recovery time for many of our case studies. Second, we study the problem of fine tuning of probabilistic-stabilizing systems to improve their performance. We take advantage of the two properties of self-stabilizing algorithms to model them as absorbing discrete-time Markov chains. This will reduce the computation of average recovery time to finding the weighted sum of elements in the inverse of a matrix. Finally, we study the impact of scheduling policies on recovery time of stabilizing systems. We, in particular, propose a method to augment self-stabilizing programs with k-central and k-bounded schedulers to study dierent factors, such as geographical distance of processes and the achievable level of parallelism.
